The Beneteau First 325 1984 vs Beneteau Oceanis 31 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department - Beneteau First 325 1984 at 34,1 ft versus Beneteau Oceanis 31 2007 at 31,8 ft. Weight tells a clearer story for trailering families: the Beneteau Oceanis 31 2007 tips the scales at 10 692 lbs - 992 lbs less than the Beneteau First 325 1984 at 9 700 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling - 28 hp for the Beneteau First 325 1984 and 21 hp for the Beneteau Oceanis 31 2007. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Beneteau Oceanis 31 2007 carries 34 gallons versus 13 gallons in the Beneteau First 325 1984. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Beneteau First 325 1984 is rated for 10 passengers, while the Beneteau Oceanis 31 2007 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau First 325 1984 could be the deciding factor.

Both boats sit in a similar displacement bracket - 9 700 lbs for the Beneteau First 325 1984 and 10 692 lbs for the Beneteau Oceanis 31 2007. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.

Both boats draw a similar depth - 6,1 ft and 5,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Beneteau First 325 1984 is rigged as a Sloop while the Beneteau Oceanis 31 2007 carries fractional_rig_sloop rigging - a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably. Helm style differs too: the Beneteau First 325 1984 uses a 1 tiller versus a 1 wheel on the Beneteau Oceanis 31 2007. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau First 325 1984 carries a 28-hp engine against 21 hp on the Beneteau Oceanis 31 2007. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

Hull speed is rated at 7,2 knots for the Beneteau Oceanis 31 2007 and 7,2 knots for the Beneteau First 325 1984. For extended cruising, water capacity matters: the Beneteau First 325 1984 carries 53 gallons versus 34 gallons on the Beneteau Oceanis 31 2007 - a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
